Toothache to the point of swelling of the face suggests that the symptoms of infection may be relatively serious, or may even be because the gums and alveolar bone have formed abscesses due to severe infection, and the abscesses stimulate edema of the surrounding tissues, thus causing swelling of the face to occur. If the symptoms are obvious, this can be treated symptomatically first, i.e. to eliminate the swelling and relieve the toothache. In addition, it is necessary to go to the hospital to clarify the cause of the disease through relevant diagnosis, and then take appropriate treatment according to the cause in order to eradicate toothache and swollen face. I. Symptomatic treatment: 1. Ice packs: Ice packs can improve skin congestion and constrict blood vessels, which can also reduce pain and reduce inflammatory exudation, improving toothache and swelling; 2. Periodontal rinse: After seeking medical attention, you can use hydrogen peroxide solution, saline, etc. to rinse the mouth to a certain extent to relieve toothache, swelling and other inflammatory reactions; 3. Medication: Use anti-inflammatory drugs, such as metronidazole, tinidazole, amoxicillin, etc. Tinidazole, amoxicillin, etc., can relieve the symptoms of toothache and swollen face, and can also be combined with non-steroidal anti-inflammatory and analgesic drugs, such as ibuprofen and indomethacin. Second, the cause of treatment: there are many diseases that cause toothache and swollen face, such as pulpitis, periodontitis, periodontal abscess, and wisdom tooth diseases. If pulpitis is serious, root canal treatment is recommended after the inflammation is controlled, and patients with periodontitis should undergo scaling and scraping in a timely manner. Patients with periodontitis should undergo scaling and scraping in a timely manner. Patients with periodontal abscesses, which cause toothache and swelling of the face, should go to the hospital for abscess drainage. For wisdom tooth diseases, wisdom teeth should be extracted if necessary to solve the recurring symptoms of toothache and facial swelling at the root. After the toothache and swollen face are relieved, attention should be paid to maintaining oral hygiene in daily life, brushing teeth regularly every day and rinsing mouth after meals, which can effectively maintain a clean oral environment and avoid oral infections caused by bacterial growth. Patients who are in a position to do so are recommended to have their teeth scaled regularly every year to remove tartar in order to reduce plaque attachment and thus prevent periodontal and gum diseases.
